Codes

2F6C - Exhaust flap (dont care)
2D2E - Angle of Throttle Valve - Intake pipe under pressure, correlation
30FF - Underboost
29D2 - Missfire Cyl 6

Is the 29D2 directly correlated to 30FF and 2D2E? Car drives fine, but once I reach about 130mph or 6k RPM the car goes into limp mode. Nothing on charge pipe at first glance and havent checked FMIC yet. Is 2D2E something worth my concern or not? (search results on what 2D2E means and how to fix it comes up with vague information)

Thanx y'all

30FF makes me believe theres a boost leak (chargepipe/FMIC). The 29D2 makes me believe you have either fouled plug/coil on Cyl 6 or it was caused by the boost leak as well (due to not having the PSI on the cylinder, causing it not to detonate correctly, causing a limp mode. Im not explaining this well, but you get the drift).

2F6C you can ignore, although i recommend plugging the trunk-wire back in for the sake of figuring out whats wrong with the car.


$0.02, take it or leave it
